GBLA10-E3/51

Overview

The GBLA10-E3/51 is a glass-passivated single-phase bridge rectifier from Vishay General Semiconductor, belonging to the GBLA series. It features a maximum average forward rectified current of 4.0 A at a case temperature of 50 °C and a peak forward surge current capability of 120 A. The device supports a maximum repetitive peak reverse voltage of 1000 V with a typical reverse leakage current below 0.1 μA. It utilizes a GBL through-hole package and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivation provides mechanical strength and protects against external physical stress
• Molding compound meets UL 94 V-0 flammability rating for safety compliance
• Terminals are matte tin plated and solderable per J-STD-002 standards

Applications

• AC/DC bridge full wave rectification in monitors and televisions
• Power supply circuits for printers and switching mode power supplies (SMPS)
• Adapter and audio equipment applications
• General purpose use in home appliances

Procurement Notes

Verify component authenticity by checking for the Vishay logo and part marking on the GBL package body. Confirm RoHS compliance via the E3 suffix and ensure the ordering code matches the specific packaging quantity required. Request the manufacturer datasheet document number 88610 during procurement to validate technical specifications against the latest revision.

Selection Notes

Select this component when a 1000 V blocking voltage is required for single-phase rectification. Ensure the thermal design accommodates the 47 °C/W junction-to-ambient thermal resistance for PCB mounting or the 10 °C/W case-to-sink resistance for heat sink applications. Verify that the circuit peak surge current does not exceed the 120 A limit under single sine-wave conditions.

Part Context

This component belongs to the GBLA series of glass-passivated bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 1000 V, all sharing the same GBL package outline and electrical current characteristics.

Replacement Considerations

The official alternative device listed in the datasheet is the GBL10E series. Designers should verify pin compatibility and thermal performance when transitioning between these End-of-Life and replacement part numbers.
